Movie Trailer Voice Generator

The best movie trailer voice depends on the film. Here is every voice in the generator reading the same line, from Don LaFontaine himself to Lazybird's own trailer voices.

In a world where every light has gone out, one hero will carry the last spark home. This summer, the darkness ends.

The famous voices have their own pages: Mortal Kombat Announcer, Morgan Freeman, Optimus Prime and Kratos. For documentaries and audiobooks, see the AI narrator voice.

The voice most people mean is Don LaFontaine (1940 to 2008), the American voice actor who recorded about 5,000 film trailers over four decades. He was so tied to the opening "In a world…" that the phrase became a joke of its own, and the film industry called him "The Voice of God" and "Thunder Throat". He died on September 1, 2008, aged 68.

That sound is a deep, unhurried baritone that leans on every key word, with a pause before the title. Here is Don LaFontaine's voice in Lazybird, cloned from his own trailer reads, reading an "In a world" line:

And Victor, Lazybird's epic trailer voice, on the same line:

Most trailer voice-overs follow the same five beats. Keep each one to a short sentence, and end every sentence with a full stop so the voice lands on it.

1. The world. One line that sets the scene, often "In a world where…"
2. The hero. Who the story follows, in a few words.
3. The problem. What goes wrong, or who stands in the way.
4. The stakes. When it happens and what is on the line.
5. The title. The name, then "Coming soon" or a date.

An example, one line per beat:

In a world where the oceans have risen, one city still floats.
Only one captain knows how.
And tonight, someone wants it sunk.
This spring, hold your breath.
Saltline. Coming soon.

Paste your own script into the generator above, or build the whole trailer in Lazybird Studio: one block per beat, with stock footage, music and captions.

Want a trailer voice nobody else has? Describe one in the Design tab above: who they are, how deep, how dramatic. You get a few takes; keep one and it becomes your own voice for every trailer. Each sample below came from the prompt above it. Helena, Gideon and Theo, three of the trailer voices above, were made the same way.

To announce your trailer in your own voice, open the Clone tab, record or upload a short sample, and your clone reads any script you type.

In Lazybird Studio, each block has an Acting box for direction like "whispering, slow and tense", plus speed, pitch and pauses. The same teaser line, plain and directed:

They told us the storm would pass. They were wrong. And now, it's here.

Victor also speaks other languages and can switch accents, so one voice can cut your English, Spanish and British trailers:
